The man who was fatally shot in Northeast D.C. on Wednesday has been identified as 21-year-old Gregory Darnell Troxler of Northeast.

Troxler was found lying dead in an alley off the 1100 block of 8th Street NE around 4 p.m. Police said an officer heard the gunshots about 3:50 p.m. and arrived within seconds.

But Troxler was already dead and the gunman was gone, D.C. Police Chief Cathy L. Lanier said at the scene, across the street from an entrance to the Gallaudet university.

The chief said that neither the shooting nor the victim was connected to Gallaudet. It occurred on the south side of Florida Avenue Northeast; the university is across the street.

Police have not said how many times Troxler was shot and have not released any information about a suspect or motive.

Police did not say whether they knew a motive in the case. Authorities are offering a $25,000 reward for anyone with information that leads to an arrest and conviction. Police can be reached at 202-727-9099 or by text message at 50411.
